Answers
Answer:
1) 71 km/hr
2) 2 hours
3) answer is 191,000 meters.
4)
Explanation:
1) Speed is calculated by dividing the
distance traveled by time. It does not
have direction. Average velocity is the
displacement (change in position) divided
by time.So therefore;284 km divided by 4 hours= 71 km/hr
2) Trip was 2 hours long.
I've covered 120km and the speed is
60km per hour.
120 divided by 60 = 2
= 2 hours
3) Meters of Travel From
Manila to Pangasinan
In the given, it was stated that
Pangasinan is 191 kilometers (km)
away from Manila. It is important to
note that for every kilometer, there
are 1,000 meters (1 km is equal to
1,000 m). If somebody is traveling from
Manila to Pangasinan to visit his or
her grandmother, it will take him or her
approximately 191,000 meters (m) to get
to the province. To be able to understand
more, a solution and the answer
will be explained below
How to Convert Kilometers to
Meters?
.
Determine the given:
1. Distance from Manila to Pangasinan
= 191 km
2. In the metric system, it is established
that for every 1 km, there are 1,000
m.
Perform the solution:
1. To get the answer, write the formula:
191 km x 1,000 m/1 km
2. To be able to get the right unit,
write the unit to be cancelled under
the possible unit. This is to cancel
the same units which are inversely
proportional to each other in the
equation.
3. Calculate the answers based on
the formula: 191 km times 1,000 m
divided by 1 km. Cancel the km units
to be left with m.
4. The answer is 191,000.
5. To explain further, if 1 km is equal to
1,000 m, then 191 km must be equal
to 191 multiples of 1,000 m.
